the bearer bars of my cot bed, AWhich'sections are round in `cross-section throughout the greater part of their length, ras shown in Fig. 4, except at the ends near the joints', Where the section is reduced, as Ashown in Fig. 3.

1ld are the reducedends oftWo contiguous sections, such as 111 and 11a or1-1Ll and dll.

12 are sideplates, shown in Figs. Landi). as connected to said reduced ends` ;1=1d means-of the rivets or bolts `-16.

The'center plates lare shown in Fig. 3 Las having horizontal anges at .their upper cdgesandsaid side plates l2-are-shown in Fig. ly asA terminating attheir innerendsin abutments adapted to `fit the undersdegof said flangcsof the center plates 13 .andlto permit the folding of said-sectionsbymotating each section around .each of-thepins' 17 asan axisfthrough an angle of ,90. degreesin one direction only. l

18, 18 are reinforcing yplates llocated -on the top and bottom ofthednner endsfofsaid sections and connected thereto by means of the pins or rivetsl forthejpurposefof protecting the inner endsof said sections `from Wear and-tear. Y

The joint of the sections 11a ;and` 111b Ais similar to therjointshown in Figs. Land 2; onlyit is inverted in position,-so as to-.permit the section 11b to be -raised insteadiof being lowered,` as the section '11 is .When forming the cot `bed into a chair, also Whencollapsr bly folding up thecot bed -for removal. It is evident from" the drawings that when only one of tWo contiguous `sections is' rotated througlran angle of-90` degrees,thc sections will thereby become `perpendicular to :each other, as showniin Fig. 12; .but `Whenfboth contiguous sections are rotated, each` through an angle of 90 degrees, the sections will close up, and theeifect -will be'the same asif-one latter to the-pantograph strips 30,` is illus-v trated in Figs. 4 and 5, in which 1S) designates one of a pair of cross-logs, to the upper end of which is secured the bracket 22 by means of the wood screws 24; said bracket 22 terminates at its upper end in the hook 23, which passes through the loop of the V- shaped bolt 21, which is secured to each of the pair of sections 11a, thereby detachably connecting each of said cross legs to said vbearer bar section.

The pantograph strips 30 are pivotally connected at each end to a stud 29, which is secuied to the cylindrical core 28, which has its aXis at right angles to the axis of said stud 29; said core 28 is adapted to rotate inside the space provided by the bracket 25 having the lower end 26 bent inwardly, as

forming a bearing for said Vother by means of a pin or rivet 43.

Each of said cross legs 41 carries at its upper end a tubular member 45 secured. in position by means of the straps 42, which are shown in Fig. 10 as secured to said cross legs 41 by means of the rivets 44.

Each of said tubular members 45 has a pair of round openings 46 at the top and bottom thereof to allow the insertion or passage of a rod for supporting any suitable objects, such as mosquito screens.

The outer ends of said pairs of sections 11 and 11b are also connected, each pair, by means of the folding cross bars 31, of which the folding joint is shown in detail in Figs. 6, 7, 8 and 9. 32 is a tubular member inclosing the inner end of each half of said cross bar 31,

' which has a recess 37 formed therein in line with the slot 38 in each of said tubular members 32; said recess 37 and slot 38 are adapted to permit the link 39 to move therethrough, and allow the folding of said cross bar 31 in one direction only.

Said link 39 is pivotally connected to the inner ends of said cross bar 31 and said tubular members 32 by means of the pins 40.

To keep said folding cross bar 31-31 in line j when open I provide the sleeve 33, which is slidable lengthwise of said cross bar, and which is locked in position by means of the pin 34, which is secured to one of said tubular members 32, and the slots 35 and 36 situated at right angles to each other at one end of said sleeve 33; the slot 35 is first made to engage the pin 34 while moving said sleeve 33 toward the left in Figs. 6 and 7 until said pin reaches the position opposite the slot 36, when said sleeve 33 is given a twist, thereby causing said slot 36 to engage said pin 34, and thereby locking said sleeve 33 in position.

Said cross bars 31 are secured at their ends to said sections of the bearer bars 11 and 11b near each end of the cot bed and inside of the removable cross legs 41.

Said cross-legs 41 are connected to the ends of the bearer bars when the cot bed is put up by slipping the tubular members 45 on to the outer ends of the sections 11 and 11b of the cot bed, in which position they are kept by friction. Said cross legs are removed from the ends of said sections 11 and 11b by slipping them off by hand, when the cot bed is to be turned into a chair or folded up.

To turn said cot bed into a chair the sections 11 are turned downwardly into a vertical position, as shown in Fig. 12, and said sections 11b are turned upwardly into a v eitical position and secured in such position by the pair of straps 47 and buckle 48, one of which straps and buckle is shown in Fig. 12.

Many changes could be made in the details o f my cot bed within the scope of my invention. I do not, therefore, restrict myself to the details as shown; but I intend to include also all mechanical equivalents and obvious modications of the same.

What I claim as my invention and desire to secure by Letters Patent is:

1. In a collapsible cot bed a pair of bearer bars consisting each of three sections foldably connected toY each other by suitable' lof a main web, which is normally vertical,

and a flange, which is normally horizontal, the flanges of one joint being on the underside thereof and the flanges of the other joint being on the` upper side thereof, and said side plates terminating at their inner ends in cam shaped abutments in contact with said iianges and adapted to abut against said flanges when said bearer bars are folded.

2. ln a collapsible cot bed a pair Vof bearer bars consisting each of sections foldably connected to each other by suitable joints, crosslegs arranged in pairs transversely to said cot bed, pantogra-phscollapsibly connecting said pairs of cross legs, said pantographs being placed lengthwise to said cot bed, each of said pantographs consisting of a pair of strips and a means for universally connecting each of said strips to said cross legs, said means comprising a bracket secured to each of said cross-legs, said bracket having a suitable bearing, a pin in said bearing, a slot in said bracket, a stud passing through said slot and securedv at its inner end to said pin substantially at right angles thereto, said stud being pivotally connected to said strip and said stud being adapted to rotate with said pin Within the limits of said slot, thereby allowing a universal motion to said strip.

3. In a collapsible cot-bed and chair combined, consisting of three sections, connected to each other, and each section containing a pair of bearer bar sections, means for supporting the same in position, and foldable cross rods for keeping the ends of said bearer bars a given distance apart,

foidabiy each of said cross bars consisting of two sections, a tubular member inclosing the inner end of each section, a recess in the inner end of each of said sections and said tubular members, a link, pivotally connecting the inner ends of said sections, located in said recess, said recess extending through said section and member to one side of said link, thereby permitting said sections to be folded on said link in one direction, and said recess terminating inside of said section on the other side of said link, thereby preventing said sections from folding in the opposite direction, combined With a removable sleeve, adapted to inclose the inner ends of said tubular members and of said sections, thereby keeping said cross-bar straight.
